I remember, and might be the case still, but one calls a "magazine" a "clip" and everyone loses their minds! Lol
So I repeatedly see "caliber" used for "cartridge" and "accuracy" just plainly misused. For example:
Someone asking what caliber a gun is, or what caliber they should get. Really, caliber is only the diameter size of the bullet. Cartridge is the word they're supposed to use, as it encompasses both bullet size and brass dimensions.
"I'm gonna switch calibers to something other than 308 WIN, so I'll go 300 PRC". Same caliber, but different cartridge is the right speak.
Accuracy…No gun is inherently accurate. That would mean straight out the box it would hit bullseye every shot. However, some can be precise out of the box. As in "Precision". It could be a group POI two feet from the bullseye, but a small group through the same hole. The "accuracy" depends upon the skills of the shooter to put that one hole group in the bullseye.
Just my thoughts on the matter.
